NCDOT developed a school impact calculator to help new schools and their consultants determine traffic impacts and how to handle potential traffic on site. The Department also provides technical assistance to schools to ensure appropriate access and circulation design for autos, bicycles and pedestrians.

NCDOT Comprehensive Transportation Plan Study [Online] http://www.ncdot.org/doh/preconstruct/tpb/planning/study.html NCDOT works with local governments to develop Comprehensive Transportation Plans (CTP that tie land use with transportation planning and seek to identify the type of access control for each facility in the long term.

The use of raised medians in urban areas has increased in recent years. Raised medians restrict access to businesses along a corridor by limiting turning movements to select mid-block locations. Therefore, a very common remark at public hearings related to the construction of raised medians is that there will be detrimental economic impacts on adjacent businesses. However, the restricted access allows more efficient signalization and traffic flow along the corridor, potentially providing more customers for the businesses.

The Missouri Department of Transportation (MODOT) is responsiblefor one of the largest state-jurisdiction road systems in the UnitedStates. Missouri has recently decided to embark on an accessmanagement program and has focused on utilizing access managementmainly to meet safety, traffic operations, and economic developmentgoals. The Missouri Access Management program development processinvolves a number of key steps. These include:

This report represents Kentuckys continued efforts to institute a state-wide access management policy, as set forth in the 2004-2008 Kentucky Transportation Cabinet (KYTC) Joint Strategic Plan. The suggestions made herein build upon the initial recommendations laid out in Access Management for Kentucky (which had also included an access management implementation plan).

This paper provides an overview of current access management programs in various states, and is one of few uncovered that focus on lessons learned during the development and implementation of the programs. Although few specific details are provided, it does include general suggestions that may be useful for the chapter on state program development. Examples of the lessons learned include hiring a large enough staff dedicated to the program, creating a separate bureau/ department/division for access management, and including a process to handle waivers.

This technical memorandum addresses the rationale for spacing of intersections that are signalized and those that might be considered for signalization at some time in the future. It includes draft prototype regulations.

Traffic conflict points at intersections are the points at which traffic movements intersect (including crossing, merge, and diverge). Numbers and distribution of conflict points have been used to evaluate intersection access management designs and safety performance. Traditionally, determination of numbers of conflict points for different traffic movements has been based on manual methods, which causes the difficulty for computerized procedures to evaluate safety performance of different access management designs.

2. Propose an access management evaluation framework that can be adopted by state and local agencies to evaluate compliance of access management policies, and the impacts of viable access treatment techniques.

This paper contains a detailed literature review of studies which have examined and reported safety of designs and operational features that contribute to managing access along roadways. It also presents trends found among the findings reported in these previous studies.

This report review methods available to state transportation agencies and local governments to preserve right of way for transportation corridors and includes a discussion of access management. In addition to North Carolina, it briefly summarizes practices available in Kansas, California and Florida.
